Xloader flash error on Hikey 960


I am trying to flash AOSP on Hikey 960. I have a question about flashing xloader img file.

The first time I tried flashing, I was using USB 2.0, and the xloader img flashed but other images failed. I then power cycled and switched to USB 3.0 on my host machine. After that when I tried flashing, I could not flash xloader; other img files flash without error. For xloader, I see the following:

What can I do to make xloader flash work ? Is it not flashing because I’m trying to flash the same xloader img file again ?

Thank you.

It doesn’t block you to use HiKey960. You could just ignore the error message on xloader.
